/**
 * Creates an attribute on the geometry or object.
 *
 * @remarks
 * This allows you to create an attribute and define the following:
 * - the group this applies to
 * - the name
 * - the type (numeric or string)
 * - the size (float, vector2, vector3 or vector4)
 * - the class (geometry or object attribute)
 * - the value
 *
 * Note that you can also given an expression to set the value of the attribute, such as `sin(2*@P.z)`
 *
